Fourier transformation image-processing technology was applied for determining the cross section fiber cell arrangement in hardwood. In this method, the disc-convoluted dot map from each cell radius with 10 pixels was transformed by Fourier transformation, and generated the angle distribution function in the power spectral pattern. The maximum value reflected the arrangement of the fiber cell.

利用傅立叶变换图象处理技术来测定阔叶材横切面纤维细胞排列，把表示每一个纤维细胞的半径为10个像素点的圈盘点图，进行傅立叶变换，再做能量光谱图的角度分布图，其最大值表示纤维细胞的排列。
